Immortalité assumée (Demonica)

Their layered personalities add depth to the story, but I wonder if this was based on myth or the author's own ideas. How did Larissa Ione develop these characters' emotional sides?

The forbidden love theme made me question whether the characters' choices were brave or reckless. How did others feel about their sacrifices and risks?

The gritty, supernatural environment feels immersive, but the sensual scenes also stand out. Was this contrast intentional to enhance the story's tension?
